Further, another exemplary embodiment of the present invention provides a control method of an air conditioning apparatus including an indoor unit and a remote controller for inputting a driving command of the indoor unit, the method including: starting a motion control function; sensing, by a sensor incorporated in the remote controller, a moving state of the remote controller; selecting an operation condition of the indoor unit in accordance with a result sensed by the sensor; transmitting the operation condition to the indoor unit; and driving the indoor unit in accordance with the transmitted operation condition.
According to an air conditioning apparatus and a control method thereof according to exemplary embodiments of the present invention, a user can change a wind direction or a wind velocity of the air conditioner by only swinging a remote controller horizontally or vertically without finding and pushing an additional button in order to change the wind direction or the wind velocity.
Accordingly, since the user can easily control an operation of the air conditioner, use convenience is improved.

In addition, a sensing unit (to be described below) sensing whether the user grips the remote controller 20 with a hand may be provided on the outer periphery of the remote controller 20. Therefore, when the user grips the remote controller 20 with the hand, light may be turned in the display window 22 or light may be turned on in the input button 21. Light is turned on in the at least on/off button and the motion control button and the user can easily control the indoor unit 10 even at night.
Referring to FIG. 3 , the indoor unit 10 according to an exemplary embodiment of the present invention may include a control unit 110, a signal transmitting and receiving unit 120 electrically connected to the control unit 110 and transmitting and receiving the wireless signal from the remote controller 20, a display unit 130 displaying the operation state and indoor temperature/humidity, a memory 140 storing information and various data transmitted from the signal transmitting and receiving unit 120, and a driving unit 150 controlling operations of a blowing unit 160 and a wind direction control unit 170.
Specifically, the signal transmitting and receiving unit 120, the control unit, and the memory unit 140 may be provided on a rear surface of the display unit 130 in a form of a PCB with chips attached thereto. That is, the signal transmitting and receiving unit 120, the control unit 110, and the memory 140 are installed on the rear surface of the display unit 130 in one module form and may be electrically connected with the display unit 130.
Further, the display unit 130 may be provided as the form of the display window 12 described in FIG. 1 and in the exemplary embodiment, the display unit 130 is defined as the same configuration as the display window 12.
In addition, the wind direction control unit 170 includes a wind direction control device 15 described in FIG. 1 and may include a vein or a louver varying the horizontal or vertical direction of the discharged cooled air. Further, the driving unit 150 may include a motor driver for driving the blowing unit 160 or the wind direction control unit 170.
Meanwhile, the remote controller 20 includes a control unit 210, an input unit 220 for inputting the operation condition of the indoor unit 10, a display unit 280 displaying the operation state and/or indoor temperature/humidity of the indoor unit 10, a memory 270 storing various data and information received from the input unit 220 or the indoor unit 10, and a signal transmitting and receiving unit 260 for wirelessly communicating with the indoor unit 10 and the signal transmitting and receiving unit 120.
Further, the remote controller 20 further includes an angular velocity sensor 230 and an acceleration sensor 240 sensing a motion of the remote controller 20, that is, vertical-direction or horizontal-direction swinging, and a touch sensor 250 sensing whether or not to grip the remote controller 20 therein.
In detail, the display unit 280 may include the display window 22 described in FIG. 2 and specifically, may include a liquid crystal panel 281 on which characters or figures are displayed and a backlight unit 282 providing light in the rear part of the liquid crystal panel 281. In addition, the backlight unit 282 may be selectively turned on/off depending on a result sensed by the touch sensor 250 in addition to control of the input unit 220.
Meanwhile, the input unit 220 may be provided in the form of the input button 21 described in FIG. 2 and the signal transmitting and receiving unit 260 may include the infrared sensor 23 described in FIG. 2 . However, the infrared sensor 23 is not limited and all sensors that are communicatable wirelessly, such as Bluetooth or ZigBee can be applied.
Further, the touch sensor 250 may includes a capacitance sensor sensing variation of capacitance generated when the user grips the remote controller 20 or a pressure sensor sensing force with which the user grips the remote controller 20.
In addition, the angular velocity sensor 230 as a sensor sensing horizontal rotation or vertical rotation of the remote controller 20 may include a gyro sensor or a gravity sensor. The acceleration sensor 240 as a sensor sensing a velocity in a movement direction of the remote controller 20 senses the intensity of the motion of the remote controller 20.
Operations of the indoor unit 10 and the remote controller configured as above will be described.
First, the user pushes the motion control button provided in the remote controller 20 to allow a motion control function to be performed. When the motion control button is pushed, the operations of the angular velocity sensor 230 and the acceleration sensor 240 are initialized and the angular velocity sensor 230 and the acceleration sensor 240 prepare for sensing an operational state of the remote controller 20. Herein, at the moment when the user grips the remote controller 20, the touch sensor 250 reacts to the gripping to turn on the backlight unit 282. For example, when the user grips the remote controller 20 with the hand, the backlight unit 282 is turned on to emit light soft light from the remote controller through the display unit 280. Of course, soft light may be leaked from on the periphery of the on/off button or the motion control button.
In this state, the user swings the remote controller 20 to set a desired operation condition and transmit the desired operation condition to the indoor unit 10.
Specifically, the user swings the remote controller 20 horizontally or vertically to allow the sensors 230 and 240 to sense the motion of the remote controller 20 and the sensing result to be transmitted to the control unit 210. In addition, the control unit 210 downloads look-up table type table data from the memory 270 and compares the table data with the sensing result transmitted from the sensors 230 and 240 to judge which type operation condition is set. The table data may be data in which a wind direction condition and a wind velocity (air volume) condition depending on the rotational direction of the remote controller 20 match each other.
Meanwhile, when the control unit 210 analyzes the operation condition, the analyzed result is converted to a control signal and the converted signal is transmitted to the signal transmitting and receiving unit 120 of the indoor unit 10 through the signal transmitting and receiving unit 260. Thereafter, the transmitted control signal is transmitted to the control unit 110 of the indoor unit 10 and analyzed by the control unit 110, which transmits the corresponding operation control command to the driving unit 150. Then, the control unit 110 controls the driving of the blowing unit 160 and/or the wind direction control unit 170 according to the received control signal. That is, the control unit controls the driving motor to operate according to a rotational velocity of the blowing unit 160 or a rotational angle of the wind direction control unit 170.
Referring to FIG. 4 , the user may swing the remote controller 20 leftward or rightward with the remote controller gripped with the hand. Therefore, the angular velocity sensor 240 incorporated in the remote controller 20 senses the rotational direction of the remote controller 20 to sense the rotational velocity or the rotational angle. In addition, the result sensed by the angular velocity sensor 230 is transmitted to the control unit 210 of the remote controller 20.
Specifically, the control unit calls a “look-up table in which a wind direction/wind velocity corresponding to the rotational angle/velocity” stored in the memory 270. In addition, by the look-up table with the result transmitted from the angular velocity sensor 230, the control unit 210 selects the wind direction angle/air volume (wind velocity) corresponding to the transmitted rotational angle/velocity. Further, the selected operation condition is converted into a wireless signal and thus transmitted to the signal transmitting and receiving unit 260. In addition, the wireless signal is transmitted from the signal transmitting and receiving unit 260. Thereafter, the signal transmitting and receiving unit 120 of the indoor unit 10 receives the wireless signal transmitted form the signal transmitting and receiving unit 260 of the remote controller 20 and transmits the received wireless signal to the control unit 110. In addition, the control unit 110 of the indoor unit 10 analyzes the received operation condition, and converts the analyzed result into an electrical signal and transmits the electrical signal to the driving unit 150. Further, the velocity of the blowing unit 160 and/or the rotational angle of the wind direction control unit 170 are changed by the driving unit 150, such that the operational state is changed.
Referring to FIG. 5 , the user may rotate the remote controller 20 vertically. Similarly as described in FIG. 4 , when the user swings the remote controller 20 upward or downward, the angular velocity sensor 230 senses the rotational direction of the remote controller 20 and the acceleration sensor 240 senses the rotational velocity of the remote controller 20. In addition, the sensed result is transmitted to the control unit 210 and a predetermined operation condition is set by comparing the transmitted sensing result with the look-up table in which the operation conditions depending on the vertical rotation of the remote controller are matched with each other.
Specifically, the set operation condition is transmitted to the signal transmitting and receiving unit 120 of the indoor unit 10 through the signal transmitting and receiving unit 260 and the subsequent processes follow the above-mentioned same control flow.
Herein, the operation of swinging the remote controller 20 leftward or rightward may be set as the control for change the wind direction and set as the control for changing both the wind direction and the wind velocity. For example, when the remote controller 20 is swung leftward, the wind direction control unit 170 rotates leftward to allow a left concentration wind operation to be performed. In addition, the rotational angle of the wind direction control unit 170 may be accumulated and changed to a uniform angle according to the number of swinging times of the remote controller 20. For example, whenever the remote controller 20 is swung once leftward or rightward, the rotational angle of the wind direction control unit 170 may be programmed to be changed by each 5 degrees. Alternatively, the rotational angle of the wind direction control unit 170 may be programmed to be determined according to the rotational angle of the remote controller 20. For example, when the rotational angle of the remote controller 20 is within 20 degrees, the rotational angle of the wind direction control unit 170 is changed by 5 degrees and when the rotational angle of the remote controller 20 is within the range of 20 to 45 degrees, the rotational angle of the wind direction control unit 170 may be changed by 10 degrees. That is, the look-up table may be configured so that the rotational angle of the wind direction control unit 170 varies depending on the rotational angle of the remote controller 20 sensed by the angular velocity sensor 230.
As another method, it may be programmed so that as the rotational angle of the wind direction control unit 170 increases, the air volume, i.e., the velocity of the blowing unit 160 also increases according to a predetermined rule. For example, whenever the wind direction control unit 170 is changed by 5 degrees, the rotational velocity of the blowing unit 160 increases by each 10% as compared with the rotational velocity of the blowing unit 160 or the rotational velocity of the blowing unit 160 depending on the rotational angle of the wind direction control unit 170 may be fixed as the look-up table type.
Meanwhile, the operation of swinging the remote controller 20 vertically may be set as the control for changing the air volume (wind velocity). For example, a control program may be set so that when the remote controller 20 rotates upward, the air volume increases and when the remote controller 20 rotates downward, the air volume decreases.
As another method, the operation of swinging the remote controller 20 vertically may be set as the control for changing the vertical wind direction. That is, the horizontal or vertical rotation of the remote controller 20 is defined as the control for changing the air volume and the air volume (wind velocity) may be changed by using an additional button or performing other type controls of the remote controller 20. Herein, by other type control of the remote controller, i.e., swinging the remote controller 20 horizontally, the acceleration sensor 240 may sense the velocity of the remote controller 20.
Table 1 shows an example of an operation condition look-up table stored in the memory of the remote controller according to an exemplary embodiment of the present invention.
Referring to Table 1, it can be verified how the operation condition of the indoor unit 10 is set according to the vertical or horizontal operation of the remote controller and how the operation condition is displayed in the display unit 280 of the remote controller 20.
For example, when the remote controller 20 is swung upward and thereafter, restored to an original position with being gripped with the hand, the angular velocity sensor 230 senses that the remote controller 20 rotates upward and a long power wind mode is set according to the sensing result, and a long power wind is displayed by characters or figures. The long power wind as an operation condition (mode) in which a wind goes far from the indoor unit 10 allows the velocity of the blowing unit 160 to be increased while the wind direction control unit 170 rotates upward.
As another example, when the remote controller 20 rotates downward, an operation condition called a speed shower may be set. The speed shower may be defined as an operation mode in which the wind concentrates on a predetermined position and the air volume of a fan increases to cool the predetermined position in a short time.
Further, as shown in Table 1, the leftward or rightward rotation of the remote controller 20 may be defined as the increase or decrease of the air volume (wind velocity). That is, the wind velocity increases or decreases depending on the rotation of the remote controller 20 or the wind velocity may be displayed as numeral values in the display unit 280.
| TABLE 1 | ||
| Control direction | Functions | Display unit |
| Up | Long power wind | Long power wind |
| Down | Speed shower | Speed shower |
| Left | Increase of wind velocity | 00 m/s |
| Right | Decrease of wind velocity | 00 m/s |
Table 2 shows an example of an operation condition look-up table stored in the memory of the remote controller according to another exemplary embodiment of the present invention.
Referring to Table 2, the operation condition when the remote controller 20 is swung vertically is the same as the exemplary embodiment presented in Table 1, however, the operation condition when the remote controller 20 is swung horizontally in Table 2 is different from that in Table 1.
Specifically, when the remote controller 20 is swung leftward, a left concentration wind operation mode may be set and when the remote controller 20 is swung rightward, a right concentration wind operation mode may be set. Herein, the rotational angle of the wind direction control unit 170 for the left concentration wind or the right concentration wind may be set depending on the number of rotation times of the remote controller 20 or set depending on the rotational angle. Since this has been already described as above, a more detailed description thereof will be omitted. In addition, a wind-direction angle may be displayed in the display unit 280 as numerical values.

Referring to FIG. 6 , a user pushes a motion control command button provided in a remote controller 20 to input a motion control command (S11). Thereafter, the remote controller is swung in a predetermined direction (S12). Therefore, an angular velocity sensor 230 and/or an acceleration sensor 240 sense a rotational direction and a rotational velocity of the remote controller 20 (S13).
In addition, the sensed rotational direction and rotational velocity are transmitted to a control unit 210 of the remote controller 20 and an operation condition corresponding to a transmitted sensing result is selected. Further, the selected operation condition is transmitted to the indoor unit 10 through a signal transmitting and receiving unit 260 (S14). In addition, a control unit 110 of an indoor unit 10 transmits an electrical signal corresponding to the transmitted operation condition to the driving unit 150 and allows an air volume (wind velocity) and/or a wind direction to be changed according to an operation command (S15).
Herein, when a predetermined time elapsed after the angular velocity sensor 230 and the acceleration sensor 240 sense the rotation of the remote controller 20, the angular velocity sensor 230 and the acceleration sensor 240 are automatically initialized to prepare for sensing a next operation of the remote controller 20 (S16).
Further, when a predetermined time elapsed after last rotation of the remote controller 20 or a user controls the motion control button, a motion control function is cancelled (S17).
Specifically, it may be programmed so that when the predetermined time elapsed after the last rotation of the remote controller 20, the motion control function is cancelled. As another method, when the user pushes the motion control button once more, a motion control cancellation command may be inputted.
Meanwhile, a smart meter (not shown) that calculates electrical charges by sensing electric power may be installed in a home where the indoor unit 10 is installed. The user may set a peak electrical power value through the smart meter and when the electrical power supplied to the home is equal to or more than the set peak electrical power value, an operation of a predetermined home appliance may be restricted. For example, when it is judged that the electrical power of the peak electrical power value is used, a standby electrical power may be sequentially interrupted by giving a priority to a predetermined home appliance or supplying of electricity to a predetermined home appliance may be interrupted.
In the exemplary embodiment of the present invention, the control methods may be mixed and as the method, the smart meter may be coupled to a control algorithm of the indoor unit 10. In other words, the smart meter and the control unit 110 of the indoor unit 10 are connected to each other in a wired or wireless method to thereby transmit a result value calculated by the smart meter to the control unit 110 of the indoor unit 10. In addition, the control unit 110 of the indoor unit 10 combines data transmitted from the smart meter and an operation condition through motion control transmitted from the remote controller 20 so as to appropriately control an operation of the indoor unit 10.
For example, the operation may be controlled by giving the priority to the operation condition transmitted from the remote controller 20 and the operation condition depending on the data value transmitted from the smart meter. The user may set the peak electrical value through the smart meter and previously set the operation condition of the indoor unit 10 depending on the peak electrical value through an input unit 120 of the indoor unit 10. In addition, when it is judged that the electrical power value sensed through the smart meter reaches the peak electrical value, the operation condition of the indoor unit depending on the peak electrical value may be executed preferentially over the operation condition inputted through the remote controller. That is, the operation control through the motion control of the remote controller may be intrinsically interrupted while the sensed electrical power reaches the peak electrical power.
As another method, only the air volume condition among the operation control conditions through the motion control of the remote controller may be restricted. That is, the wind direction condition is just performed among the operation control conditions through the motion control of the remote controller and as the air volume condition, an air volume condition set depending on the peak electrical power value may be performed. Therefore, the electrical power supplied to a fan of the indoor unit 10 decreases, such that electrical power of an amount smaller than the peak value may be supplied to the home.
